Get yourself some potting soil, however many containers you’ll require, your starter tomato plants, and a trellis (or two). 

Trellises are plenty useful if you’re growing out of containers or if you are planting your tomatoes in your backyard. A trellis will work in ensuring your plants are kept upright. This makes it easier to prune the plants and to harvest the crop. Plus, it – the trellis – reduces the potential for pests and diseases impacting your plants.

Your containers should be 12 x 12 inches (5 gallon) or 14 x 14 inches (7 gallon). You’ll want there to be some holes in the base of each container for drainage purposes.

Add your potting soil and trellis to the pot. You’ll want the trellis to stand upright and to remain stable.

Time to dig a hole in the potting soil. Then, remove your tomato plants from their original containers and position them in the new containers.

The root ball of each plant should be at the trellis’ base. This will allow each plant to enjoy full support as it grows.

Plant your tomatoes deeply – down to the first two leaves on the stem. Remove those two base leaves by plucking them off. Unlike most other plants, tomatoes do very well when planted deeply. This encourages more root growth.

Irrespective your tomato plants are in containers or in the ground they’ll need plenty of water, and, of course, plenty of sunshine. Ideally, tomatoes want at least six hours of sunshine daily. Plus, they’ll want a minimum of an inch of water each week. When the weather is very hot, make that two inches of water weekly.
